How effective is it re-flowing the wifi module on the 4S?

I had a few 3G iPhones with no wifi and the re-flow worked for a few days and then the problem came back, you had to re-ball it to fix it properly.

How effective is it re-flowing the wifi module on the 4S?

Thanks guys, old method, but works 100%..

No waterdamage, no drop, looks as new iP 4S, but 3rd client with these problem..
Same problem on two 4S of their family, just by connecting on someone WIFI conection...wifi greyed ....interesting

Only problem for first time doing, was disambling..complicated than iphone 4..

Remove blacksticker, rehoot, assembly (hardest) and ready to go....

Payment solid one, as much as you think that will charge someone for disambling an iphone, and a cofee...
otherwise two days of working wifi its worth..dont mention that have cases that has been months working with these method..

thanks..
