Hello, I am new here to the andriod forums. I am having the same type of problems. No data connection because I couldnt update my PRL. I put clockworkmod on my sprint HTC evo 4g and then installed cyanogenmod 188.8.131.52 then the gapp file, well i tried two different gapp files that didnt work. I wiped/factory restored then wiped dalvik then formated my system folder then installed from zip first the cm7 then gapps-20110307. That did give me cm7 but I had no market, no data connection no internet or tethering so a buddy of mine told me try a different gapp so I then repeated the process by wiping both places and formatting. i then reinstalled cm7 and use gapp-20110504 hoping it would work. I was able to get the market working but only in the way that i could click on it and have it tell me no data connection is available. I tried to open my browser and got the same error message. I did everything the way I was supposed to but it didn't work. Am i missing something here?
