sorry you cant them back or try via connecting usb

yes i have a prepaid sidekick id, and sidekick 3
if you go on the tmobile website or bestbuy website they show the sidekick on the prepaid service list.

no ure done dude , unless you try to check main sim contact might be in there

Call t-mobile if the phone is stillunder warranty

If not then follow this procedure.

Fix Sidekick White LCD Screen

It will usually fix the problem

try taking the battery out. mine went black and wouldnt do anything when i tried to press buttons so i took out the battery and hit the on/off button and it came back on but i didnt save anything to my sim card so i lost all my information

You need top purchase the sidekick plan from Tmobile for an extra 20 dollars a month. It includes unlimited text messaging web browsing and the use of the catalog to download stuff

to get photos on the sidekick you have to email them to your email account that goes directly to your phone.

Your phone needs to sync back with T-mobile's network.
