I hope someone knowledgeable about how-things-work can help me with this. We bought an unlocked HTC G2 for use with a prepaid non-data SIM card, so my senior citizen mom could use it on a trip overseas and also in the U.S. Problems began when a language translation program (touted to be independent of internet, no data needed) began asking us to pay for it even though we already had. It said to login to Google. We can't, there's no data plan. Then it started asking us to login to Facebook and Twitter. We don't have Facebook or Twitter accounts, and again, no data plan. Next thing we knew all apps installed disappeared from the phone. App icons I had removed are back in place, phone appears to have reset itself to the day we received it. Even books I'd sent to the phone via Bluetooth are gone, along with Aldiko from Android Market. Does Android market control the entire phone even when there's no data plan? Could it "reach out" and delete my apps without using internet? Is there some kind of rule that one can't use downloaded apps (even those purchased) unless Android Market keeps verifying them via a data network? I don't know what to do. The man at the T-mobile store told us the phone was defective. I don't know if that's the case or if I'll have the same problems on any Android phone without data. I don't want to go through a return/exchange and have this happen all over again. Thanks in advance.
