I have a sprint 700 palm treo would like to flash it to alltel my alltel 650 palm treo does not work any more

Could be hardware related but I would confirm your Treo OS is the latest version. There have been a couple of updates since the Treo 650 was launched. Note that the updates are service provider specific (i.e., if you are on Sprint PCS make sure to get the Sprint PCS specific update, etc.)

If the phone is new to you, (different story if it was working on cingular before .. let me know if it was)
It sounds like it is sim locked, the phone needs unlocking.
If you can contact the previous owner and ask them what network it was on and borrow a sim card from that network it will verify the phone isn't faulty or blocked
The previous owner may be able to get it unlocked for you via there provider else somewhere like www.650unlock.com will do it for about $15 (I'm not recommending them, just one of the first in a search) Its worth googleing "treo 650 unlock" and shopping around also check 650 forums for recommendations

Best of luck

If you are a Verizon customer with a Verizon account and the Palm is a Verizon labeled phone, the support people will be able to assist you with transfering the phone to your account.

Since this is a Sprint labeled and logoed phone, there may be a bit more work to get this locked to your account. You will need to have a Verizon technician assist you by calling their support line and explaining your situation. You will need to verify with them that the phone has a clean ESN and they will ask you for that number to check. They will be able to get you on their network if the ESN is clean and your account is in good standing. There are a number of sites and blogs dedicated to this very issue. Just search for your phone on the internet and you will find them and what to do to have your phone switched over.

As far as changing the splash screen from Sprint to Verizon, that requires software and understanding where the image files are located. This is not a task for the novice. Again, when you look through these sites, you will find the information on how to change these items, how to back up your phones data dump, and how to read the different categories these items are located in. Be careful...you can destroy your phone if you are not careful.

Good luck.

You can do a soft reset by pressing the small indented button on the back with your stylus,: or you can do a hard reset by removing the battery and pressing the same button on the rear with your stylus. I would try the soft reset first, as the hard reset wipes all your data.

I wish to unlock my sprint based [Palm TREO 700wx] so i may use it on another network, can I?

Verizon suggested a hard reset on my 700w for the same problem. (Hit soft reset and power/end button at same time and hit up on keypad when prompted to reset everything and reboot)
you will loose all of your features but they say it fixes 5/10 times...

It did not work for me but I wanted to share in case.

hi, on the hotsync software (palm desktop) there normally is an option were you can decide what to sincronise and what not. if you go to hotsync (on the top next to tools)and then choose personalise, then look for the calendar and click change, choose the one you think is correct. dave ;)
