There. The title pretty much says it.
They're just looking into it. That is according to Wireless Week who got their information from media sources. However, this is not as far fetched as it might soon since T-Mobile already offers Mobile web surfing and unlimited texting at $35 for the G1, which is the same price being considered as the new Internet plan to be offered across their portfolio.
This is a good move as T-Mobile and the other wireless providers are embroiled in a class-action lawsuit over texting prices.

Note: While all wireless providers are inherently evil, T-Mobile did bad when they tried capping the G1's 3G acess at 1GB. Now, the cap is closer to 10GB. I like to think Google's influence has sort of rubbed off. iPhone and ATT, Verizon, and Sprint: your move.
