I looked at Straightalk, too. Wish they had a pay as you go plan, rather than monthly, with similar discount. I like options. There are several of of these non-contract companies but not much chat about them. Thanks for starting the thread, op. I have also heard similar talk about the 2Gb. cap, so that poster didn't just make it up. It might not be in writting but it seems to be what the users are experiencing.

Be kind to the devs! Without them, XDA is just a bunch of jerks bickering.
