There is a Thanks button at the bottom of the posts you want to thank. You can only 5 thanks a day because people where abusing the Thanks system. But you don't need to thank me, everyone should try jailbreaking, it's not that hard and you will be blown away on all your iphone will be able to do.

hi, iphoneconnie! I wanna thank you for the reply you made to my "this is me" thread about jailbreaking. ....ehm, I might sound like a forum virgin, but how do i "thank" you, so that it gets into your "thanks" count?
