You need to get the unlock code for that specific phone. You can get it on Ebay (safe) for about 10 bucks. I did it just last week. There are several vendors, don't pay more than 10.00.

How to unlock my Blackberry 8100 from Tmobile to use it with ATT


Well if you are tied to a particular network all you have to do is call up the customer help line of the service provider and ask them for the unlocking code, which will be provided to you for a nominal amount of money.
You can also get the unlock code through online..........i will suggest the website http://www.blackberryunlockingcodes.com which is doing good service .....you can approach this website.

No service - sometimes service for short periods of time


If you have ATT that explains it all. If not, call your service provider. Sounds like you have a defective phone! Rip them a new one!

At&t 8525 to tmobile wing


NO you can't do that but you can unlock the CID and sim and then flash a custom hermes rom from xda-developer.com but first you need to run thi unlocker to unlock the sim and CID.

http://pof.eslack.org/hermes-unlocker/

Run this unlocker on your phone. Follow the instructions exactly. Don't unlock the CID unless you planning on installing another custom rom other than ATT on it.

Treo 680 charging light flashes red when disconnected from charger


Have you activated phone yet? When phone is activated and in service it flashes green. It's hard to believe it would flash green without a SIM card, as there is no service...unless AT&T is providing emergency service only and you're getting a flashing green which means you're in range of their towers.
