Default Spoof MMS User Agent?
Does anyone know if there's any way to spoof the MMS User Agent on this phone? As a T-Mobile customer, I'm forever stuck with the '120x160' lockdown on received MMS pictures anytime I use an unlocked phone. I've been able to get around this with certain other brands (Nokia, WM), but I haven't come across anything concrete with this phone.

Doing some searching here, I've seen some custom .apk files for specific Android phones (G1, Hero, N1, etc.), but nothing more general.

Can anyone help me with this? I *can* send and receive fine; I simply receive at a tiny size. I've tried using Handcent, the stock app, etc., but I know it's T-Mo's MMS server doing this to me because it doesn't know this model.
