My otherwise healthy G2 lost the ability to read a SIM card. It turns on fine, runs apps fine, connects to wifi fine. It does everything perfectly except make calls, send texts, and pick up a data signal. It is, in effect, less a "phone" than a sort of pocket computer. The guys at T-Mobile said the wiring in the SIM card reader must be at fault. The guys at the repair shop said the T-Mobile guys had no idea what they were talking about, then worked on it for three weeks before giving up. They suspected the motherboard, possibly from delayed water damage. Warranty is a) expired and b) voided due to said water damage. I'm due for an upgrade in a few months, but as I said in my other thread, if I can't fix the G2 I'm stuck with a G1 running Donut. I'd probably pay up to $100-150 for a successful repair since I'll save some money on the upgrade if I make it to 22 months (there's an 18-month discount, but the difference is significant). Any ideas? Anyone else encountered this issue?
