Dear All

Sorry for my Bad English....
I use iphone 3G 8GB, a few days a go I was open it because it can read a Wifi Network. After I read some tutorial on Internet that suggest to re-flow the IC Wifi, so I using air hot soldering to re-flow the IC at the back of the main board.
After that I also clean up all the IC of logicboard using Alcohol. Finally I re-flow all the IC at the logicboard for just a few seconds to dry the Alcohol.
When I assemble all the parts of the iPhone back & try to Turn it On, it won't turn on.
Are there any suggestions to make my iPhone back to normal again or maybe there is reason why it could happen to my iPhone. Please Help.

Regards,
AlNania
