Hey, just after some advice about MyWi - its 20dollars. Tetherme is free. I have been using Tetherme to share my iphone 4s 3G with my iPad 2 (wifi only) ...so, that works fine. What exactly does MyWi do? Is that like wifi speeds from anywhere you are? Is tetherme using my iphone data allowance? ...the description says its a direct vpn? Connection to the iphone & so 'shouldn't use your allowance'.
