To answer a previous concern, yes you can access secure websites using metropcs. You can pay your bills using it.
As far as MMS, if you read thru the linked thread, you'll notice we've been working on it and only have had partial success..
Personally, I gave up trying and went Sprint SERO and no longer have MetroPCS. Life became much easier.. Until they cut MMS off lol.. haha point at me..
With Houdini and MetroPCS opening up their network to other carrier's phones, it has become much easier, but they still won't leak a hint about MMS server settings.
Even if you go with Houdini / MetroFLASH your phone to their system. It only gives you Talk and Text. If you can find out how to edit your web sessions and/or internet settings, using what I posted above you should be able to access the internet, provided you have that service enabled on your Metro account.
Also a recent personal observation, is that @metroWEB is much faster than before even though it's still only 1X in my service area. The signal quality has also improved. Where I used to be able to make fun showing off my Sprint signal bars where MetroPCS had 1 or none.. Now I am put to shame at times..
Enjoy,

P.S. The default MetroPCS homepage might not be available for your non-MetroPCS phone, so when you first connect you may get an error. Don't worry, just enter the URL you wish to load and have fun!
