Even though I didn't go to Tmobile, I left Sprint after 11 years after I bought my Nexus 4.I am now on Straight Talk using an AT&T SIM card. My 3G speeds are faster than my Wimax speeds on my Epic Touch 4G. Do to they way that Sprint treated my as a customer by charging me for a service that they failed to provide, I doubt if I will ever buy another phone on contract. From here on out, it will be unlocked GSM phones for me. I never want a company to fail because of all of the jobs that are lost. With that being said, Sprint can crash an burn for all that I care. You can look at all of the forums on any mobile site and see all of the complaints of Sprint customers. The might turn the sinking ship around, but I doubt it . The end is near.
