Thanks for you work on this app, a lot of people want this on their phones! From my perspective, fAPN wasn't necessary, as the SMS I got from O2 when I put the SIM in set up everything that was needed there.

I guess the only real challenge left is to get the app to use the right connection (ie GPRS) automatically? I was wondering if this could be related to which interface the application was binding to? e.g. should it not be bound only to phonet0?

Also, I notice resizing is pretty slow - could we have some options in the app for this? E.g. HQ(slow)/LQ(fast) all based around the assumptions that the images would have come from the built in camera.
As the MMS images themselves are pretty small, how about caching the resized images? It wouldn't take much space on the device (limit could be configurable option), and would be really helpful - especially with the connection thing and the resizing delay... sometimes I find by the time the image has been resized my connection has swapped back to WLAN... so it errors, so I'm back to the start.... A resizing cache would be a simple optimisation.

Anyway - thanks for writing this app. Much appreciated.
