Help Do I need to have AT&T change my data plan?

[MattMJB0188]

I am coming from the iPhone 4s and just got the Galaxy S II (i777) and my speeds aren't as fast as they were with my iPhone 4s. I can pull at least 5 mbps down at home and I am barely getting 2mbps. My data plan is "Data Unlimited for iPhone 4s" and I am using a new MicroSim card with an adapter.

I am rooted using the rom UnOriginal. Do I need to have AT&T change my data plan and get a regular sim? Thanks

You might try and getting a new sim from an AT&T store. They shouldn't charge you. I had to do this when I left my Captivate for my SGS2
