When the device is in a very weak or no signal area for a long period of time, it only comes back on to GSM when returning to a good signal area. I have to do a hard reset on the device to get it back on to GPRS. Anyone know why or how to overcome this? Many thanks.
You may need to upgrade software, but if you have a sim card pull your sim card and battery leave them out for a couple minutes, put phone back together and see if it resolves your issue, could be a glitch in the network.

Remove your device battery, insert the appropriate SIM card and then restart your handheld. Next, open up your Manage Connections options again. Select Mobile Network Options and then change the Network Technology from 1XEV to GSM/UMTS. (Remember, if you want to go back to CDMA, you need to switch back the network technology option.)
this device have a weak flat electronic connection between body & LCD
& because of doing open and close the LCD periodically it might crash and you have to send device to an expert to replace that part
Verify that the OEM Charger and Battery are being used.
Only the AC charger, Car charger, or USB data cable that came with
or was created for the device should be used; others can damage the
device and/or battery.
Is the device warm?
When using the device for prolonged periods of time, such as when
you're talking on the phone, charging the battery or browsing the web,
the device may become warm. In most cases, this condition is normal and
therefore should not be interpreted as a problem with the
device.The device has a protection feature that if the device becomes
too warm (due to use of GPS while charging, BT while charging, using the
device as a wireless modem, etc), the auto protection feature will be
triggered and the charging process will be stopped. Once the device
cools down, the device will then begin charging again.
Check the USB Port on the device for any bent or misshapen PIN's.
If some are found, that is the most likely cause and this is considered physical damage not covered under the Warranty.
Remove the battery and inspect the contacts.
Remove any debris/residue found on the device or battery contacts with a soft, dry cloth.
Look closely at the battery contacts on the phone to see if they are bent out of shape.
If they are bent, the device will need to be exchanged.
Try charging the device (try different power sources as well as chargers):
Plug in USB to device and PC; is the LED indicating that the device is charging?
Note: If the device isn't charging while connected via USB to a PC,
go to Start>Settings>More>Power>Power Management and make
sure that "When device is turned on, do not charge the device when
connected to the PC" is set to OFF.
Plug in AC Charger to device and outlet; is the LED indicating that the device is charging?
LED indicators: Charging is indicated by a solid Amber light on the upper Left side of the face of the device.
Note: If the battery is completely dead, the light will be a solid
RED for a few seconds while it is charging; once the device has enough
power to turn on, the light will turn to Amber.
Try another Power Source.
Try a different outlet to rule out that as the issue.
Try another battery in the device.
If another battery doesn't work, perform a Hard Reset.
If the device powers up after Hard Reset, test the unit for a few
days. If issue returns, device can be considered for an exchange.
If device shows charging with one (AC Charger or USB) and not the other, issue is with the accessory. Replace accessory.
If device will only power up when attached to charger (AC or USB) it is likely the battery needs to be replaced.
Device won't hold a Charge The life of the battery between charging sessions will vary depending on which features of the unit are being used.
Verify the you are using:
OEM AC Charger
OEM USB Data Cable
Fully charge the battery using the OEM AC Charger
USB and car chargers are trickle chargers meant to get the user through until they can get to their AC Charger.
If the device is not lasting the advertised Talk time, with minimal use, try another OEM battery in the device.
If the battery life still is not meeting the advertised Talk time
(with minimal use), the device will need to be repair/replacement.
Device won't Power on
Attempt to charge the device.
If the battery is dead, the device will need to charge for a few minutes and then should power on once this happens.
Attempt to power the device on by pressing the Power Button for 3-5 seconds.
If the device doesn't power in, perform a Soft Reset using the stylus.
If the device still doesn't power on, perform a Hard Reset.
Try another battery.
If the device still will not power on, it can then be considered for repair/replacement.
Handset Powers off
Make sure that the device is actually powering off and not just going into hibernate mode by pressing the power button once.
If the screen comes back on, the device is not powering down.
If possible, check the battery level by going to Start>Settings>More>Power>Power Management.
The charge should be no lower than 10%; if it is, charge the device and retest.
Try another battery in the device.
If the device stays powered on with a different battery, the issue is with the accessory not the unit.
If the device still powers off with another battery, Hard Reset the device and retest.
If the issue remains after the Hard Reset, the device it can then be considered for repair/replacement.
Is the phone SIM unlocked, CID unlocked or both? The quickest solution (if you have an uncorrupted ROM) is to do a hard reset, insert your SIM card and see what you get. It that doesn't work, you should probably start from the beginning and flash a new ROM. You need to know what version of Windows Mobile you are running and the device's unlock status before we can point you in the right direction. When you have that info., PM denco7. He is the expert on flashing ROMs and can advise you on which custom ROM to load on your device and the steps you should follow to do it. He really knows this stuff and is happy to help. Thanks.
The 3G icon appears only when you are in 3G reception area and you are receiving 3G signal. Ensure that you are in the 3G reception area and signal is received .some areas there may be weak signal it may also cause to select Gsm mode
Try to hard reset your device. Your device will return to its factory defaults. Your device's user manual tells how to do it. Just in case you don't have it, press and hold both softkeys. Whilst keeping them pressed, briefly press the reset pin with the stylus pen. Release the keys as further instructions come up on-screen. Just follow them.
Hope your device comes back to life soon.
Press and hold the Left SOFT KEY and Right SOFT KEY, and at the same time, use the stylus to press the RESET button at the bottom of your device. You will be presented with a menu saying 'press R to reset, X to exit', if you press R Your device will be set back to factory default settings. (The L/R soft keys are the "- -" keys just above the start and OK buttons)

When I lose signal strength, which doesn't take much with this device - It can sat in the same position and go from GSM to EDGE through no movement. A sure fire way is to turn the device off and then back on. This always works for me.
Another trick I have discovered is by switching networks - options/ mobile network and changing network selection mode from automatic to manual and allowing to select available networks which can take a minute or so choosing a selection and then going back in and changing back to autmatic.
