3G Plan Questions

[ranmasaotome510]

So i recently was on T-Mobiles site purposely seeking for a cheap plan.

My intention during plan custimizaition was to get a cheap plan, a free phone, and to just take the SIM for use on something else.

So i concocted a plan of 300 minutes (29.99), with "Unlimited Web + Unlimited Messages for phones" (19.99) *what A Steal!*. Of which comes to a total of $49.97 Monthly

Now heres the part were i start asking questions. While i know its feasibly possible to just use any carriers SIM on any unlocked GSM Device, what i want to make sure of is that this plan with the "Unlimited Web + Unlimited Messages for phones" would work on just about any Unlocked GSM Device.

The reason for my paranoia, is because of my attention to the "For Phones" on the data plans detail. Am i going to be limited on web browsing, and/or are they using some proxy to route data to only websites? is it strictly cellphone browser limited? My point is... Can i use this "data plan" on any 3G Capable GSM Phone and/or device? And not be bogged/limited to only special "service requirements"?

Please someone ease my confusion
