I GOT IT!... ok, so finally i think i figured it out.. i was one of the people who could not get it to work after trying all of the methods on the first post, so this is how i did it... i tried hard reseting = didn't help.. i tried messing with the ##3282# and ##778# codes and values and nothing helped.. so i noticed that after the hard resets the values i put in were still there, showing that a hard reset doesn't do anything... so then i tried the ##RTN# reset and found that it changed back the original files, but it still didn't fix my internet.. so finally i flashed over to the stock sprint rom(found in upgrades forums) and then did the ##RTN# update again..so basically here is what you should do:

Alternate Internet Fix (if nothing else helps):
1) Backup all data (contacts, etc) using a program like PIMBackup or something like that.
2) Flash back to the stock Sprint rom (in upgrade forums)
3) Do the ##RTN# (##786#) and enter your MSL.. then go to menu and reset.. hit ok and then ok again to reset the device.
*** just so you know this reset will keep your internal storage.. nothing on that directory will get deleted***
4) Let the stock sprint custimizations run.. after they are finished your phone should automatically soft reset and then your done!

ps.. if your data still isn't working make sure your active profile is set to 1 (##3282# menu)
NOTE: i didn't have to do this so you should'nt have to.. but just in case i think it's a good idea

so this is what worked for me after nothing else does.. for those of you who still can't get your data to work try this and let me know if it helps..

Thanks guys for sharing and helping..
