I've entered APN settings 3 or 4 times on this unlocked G1 I just got from ebay. Whenever I finish I always select menu > save settings but when it goes back to the apn screen there are no APN's saved. I even tried resetting to defaults (which should have brought all the T-Mobile ones back) but not even that worked, its still just blank. I'm trying to get it on AT&T in US by the way. Anyone seen this before?
