Well you have to factor in the price and what they offer. If they give you over 2.5GB of data under 60 then you will see those telcos doing better. Look at what happen to H2O, they started great and then they went to the 1GB max and people left in droves to Straight talk.
Carriers that didn't pay the dreaded iPhone tax are feeling the pinch and customers are leaving in droves. Smaller players such as MetroPCS have been hanging on by the fingernails since iPhone 4.
T-Mobile has been swimming against the tide as well and iPhone 5 is only accelerating customer defections.
We are being assimilated by the Borg great apple.
The wireless market is NOT only about the IPHONE or ANY one handset... it's about the bottom line costs and the smaller carriers are fighting a tide, which is a race to the bottom on the most service for the lowest price.. anybody who think's it's always about the iphone speaks only to a demographic that can obviously afford a $649 phone and are not the segment of customer tmobile & metro are going for..
reply to Irun Man And TMO-USA never gave in, but yet support it and are able to still do what they need to do and are picking up pace. That money that went to Apple won't ever be earned back fast enough to give companies like Sprint what they need.
