Bought a droid from Best Buy - new account - new activation on the 10th. Kept it for 4 days - battery life blew - so I exchanged it for an Eris. Finding that the battery life on this handset is even worse! Can't get through an 8 hour work day of normal use. At least the droid could do that. I'm still in my first 30 days (first 10 actually) Wondering if I can exchange back to a droid? Can't find anything in the fine print about this - just wondering if I only get 1 exchange - or how the policy works?
