I recently upgraded to iPhone 4 from The Original Revolutionary iPhone on which I had a GoPhone Pick-Your-Plan (via jailbreak/unlock) which (due to rollovers) accumulated almost $500 credit. I cancelled the account, and they gave me 2 months until credit expires. What can I do? How can I spend these (pretty much useless now) $500 in 2 months and have some fun in the process? (I already send a few SMS's to myself ("hello *********!" - "hello idiot!" ) and got charged 40 cents for each (sent/received, 20 cents each)... that's pretty much all fun so far) Thank you for your valuable suggestions.
