Help! Computer doesn't see iphone

[stfudvs]

iPhone 4 4.2.1 snowbreeze ipws, windows xp, iTunes 10.2

Last night I used snowbreeze to make custom firmware, installed fine, updated cydia and installed sbsettings, gridlock, perpagehtml, and now iTunes or my computer don't pick up iPhone

Tried several reboots, reinstalled iTunes, checked apple device manager, and a new USB cord... I'm lost as what to try next

Plug phone in, makes correct sounds, starts charging, but no iPhone in iTunes or on 'my.
Computer' , doesn't show up in device manager either

Ifunbox can access the iPhone tho no problem

What other steps shall I try
What happened?

It had no problem seeing my iPhone for a few hours after the fresh install and cydia packages

seemed to happen randomly ?

Do you install anything weird?or even new?

Try possibly going into DFU mode and then using a program to kick it out...NOT ITUNES.

or use tiny umbrella to enter recovery.. and then exit it.. it might work.. try reinstalling your itunes again but first uninstall itunes.. get the latest version.. it might be some issue with your iphone drivers.

thanks for the help, unfortunately for me none of that stuff did anything for me

however i was able to get the computer to see the phone, so i know it must be itunes, going to downgrade to 10.1 as i see other having same issue on the apple support forums
