[yearn]

I been having the exact same problem the last week and so has my buddy thats on VZW.
I flashed the stock 6.5 ROM and checked out what version Arcsoft was in it then searched for it, and found it.
reflashed Mr.X's 2.5 ROM and installed this cab and it works perfect.
He is runnings MightyMikes official 2.1 and it worked for him also.

Also this works fine with HTC messaging in X's ROM without changing amy server settings or anything.
