Re: Good T-mobile has the advantage here because of the current 3G network in place. Even if they couldn't upgrade towards LTE the fact that I can pull up to 20Mbps on a HTC One S and 8Mbps on a Galaxy Nexus unlocked proves that the investment they did towards their 3G network has paid off with real world results. Sprint who has EVDO cannot provide such speeds without a large investment towards infrastructure and with the many changes from Nextel too Clearwire and now LTE. This caused Sprint to lose money and in the process question the overall thought process based on those decisions.
Althought Sprint Vision sounds great, this has been on the board since the Nextel merger and only now they are actually talking about some kind of deployment towards that idea.
Sprint will be forced too upgrade towards LTE for data speeds too even keep up with T-mobile's 3G network.
If we exclude data speeds from this equation then a more equal footing will be coverage. I believe Sprint has more coverage than T-mobile and I also make the assumption that they do have a roaming agreement with Verizon for 1XRTT.
Once again I would prefer T-mobile too improve coverage over speeds. One can argue that coverage and speed goes hand in hand but what matters most is still it's primary function and that's a phone.
So with that said....at this time T-mobile has the advantage and Sprint will need to reorganize itself before it can make any progress which will make any progress slow and painful.
The merger with MetroPCS will assist T-mobile with prepaid accounts and damage Sprint's MVNOs in the process because of data speeds.
