iphone4s pdanet & Mywi

Hello everybody

I have an iphone 4s & i tried to install mywi on it but it doesnt work i tried every thing ! mywi (rock) ,, my wi on demand ,, mywi cracked , also mywi ! total failure & tried 2 sources i woowiz & sinful iphone !!! it gives me errors while installation some times it went good but in the last it gives me errors & have downloaded app.. then i just removed it finally !

Now I installed a pdanet it is installed & works ! now the problem is that the internet connect & appears on my laptop & also worked good but when i go to wifi from my hone settings & cant find it even if I tried to add it myself !? what is that ? shouldnt it also work on my phone also ?

then now it gives me that exclamation mark that it cannot connect !

Is there any solution for that phone thing to find my own wifi ?
& is there any solutions to install mywi ? what is the cause of these errors while installing ?

wifi or pdanet ? I really dont know what to do ?

Thanks ,
