Question about RIM BlackBerry Pearl 8100
Bought a new BlackBerry 8800 but I need to unSIM lock to use zain SIM card. I've been asked to provide information by extracting from the phone using BB-READER soft ware so that they can give me the unlock code. I have done all the steps but one - the software says the GSM radio is not connected. What shoudl I do?
Option # 3: T-Mobile or Cingular, your carrier
Yes, you can ask your carrier for an unlock code for your Blackberry and guess what, they do it for it Absolutely FREE. So, what is the catch? The only condition which atleast T-Mobile imposes on its customers before it gives out the unlock codes for the Blackberry Pearl or any other cell phone is that you have to be under the contract for atleast 90 days or 3 months before they can give you the unlock code. So, if you have the patience, I would recommend that you wait for this 3 month time frame before calling up 611 from your T-Mobile phone, talk to customer service and get your unlock codes.
In my search for the Blackberry Unlock codes, I found out that a lot of people mess up before they have no idea how to enter the unlock codes correctly. So, follow this method to enter your Blackberry Unlock code

I have the same problem. The following solution may apply; here is how to IDENTIFY the problem:
(1) Phone doesn't connect to desktop software through USB but will through BT (if setup)
(2) Phone doesn't charge whether USB-computer, USB-wall, USB-carcharger or does sometimes but you are not sure why it works sometimes but not all the time
(3) If you hold, lean, twist, or jiggle the plug at the phone, it may charge or the charge icon may show briefly
(Also) Plug is noticeably loose or comes out
if plug is torn loose, damaged, or comes all the way out, go to this site and follow along in kind http://computerguru365.blogspot.com/2006/02/diy-blackberry-usb-repair.html
If plug is simply intermittant: remove all power and the battery, open your phone, and carefully redo the solder joints of the plug. If you don't have a SMT (surface mount) rated soldering iron w/ tip, you can use the radio shack standard but be sure to only apply the hot tip in pulses (less than/up to 50% of time, less than 3sec each touch) so you don't heat damage the surrounding components.
Because the plug gets tugged to the sides causing the solder joints to crack (microscopically). At first I had to lean books against the plug but then that quit working as well.
This approach also worked on my laptop which quit charging when plug torque flexed the motherboard and cracked the solder at some surface components near the plug. I found out which components when the varying the force of my multimeter tip cause the component to show open and normal across the solder joint
