T-Mobile offering Gmail access on G1 phone for free

According to Phones Review they say that T-Mobile may possibly offer Google Gmail email access to all their users for free, yes no data plans on the G1 Android Phone.

If this plan does go ahead this means that having a no data plan or extra monthly fee would win the hearts of millions, it seems that T-Mobile and Google may possibly be thinking of free Gmail access ad supported and this is where they would earn their money.

Could this new plan have risks hidden within though? This is the question that many will ask, T-Mobile at the moment charge for data-access and it is these data access charges that have become the best part of T-Mobile rising quarterly revenues, so how will this no data plan affect them.
