I've tried everything to get my Metro PCS internet setup. Please help!!!

[Jbbrack03]

I'm banging my head on the wall trying to get the web connected on my HTC Touch Diamond (6950). I got it flashed at Metro PCS today and got my number. So I came home and tried to do the internet connection tutorial (called: Offical Web And MMS Setting For Metro Pcs!!!!). That didn't work. So I just got done installing Juicy 4.3 (the only one I could find for the diamond) and now I still have no idea how to connect to my web. I do have the $45 Metro PCS plan that includes unlimited web access.

So I've done my connection setting in the ##778# menu (as per the tutorial on this site). Then I did the settings in my connection manager. I try to connect and it says that it can't find the selected proxy server. Everyone says that using a custom cooked ROM makes connecting to the web easier, but nobody says how. To me it looks the same as it did before I installed the ROM (other than the obvious lack of Sprint apps and the fancier screen effects). What does installing the cooked ROM do to help me connect to my web?

Also, the tutorial about connecting to Metro PCS web mentioned something about renaming these files:

Windows\iota.exe ---> windows\iotaOLD.exe
Windows\iotaconf.txt ---> windows\iotaconfgOLD.txt
Program Files\IOTA ---> Program Files\IOTAOLD

I searched all over my windows folder (and the folders around it) and I can't seem to find these files at all. Now I did look for the HTC_CM_Guardian.exe so that I could replace it (it was there before I updated to the Juicy ROM), but I'm assuming that this was removed as part of the Juicy 4.3 ROM.

I really don't know. I'm sure that I could be going wrong in several places. Can anyone offer some guidance to help me get this task completed? I'm really ready to enjoy this phone. Any help at all would be highly appreciated!

EDIT: I carefully read a ton of tutorials (only half a day's worth) and now I'm a lurker? That's a little funny to me... LOL
