I have been wanting to switch from T-Mobile to Sprint since this phone was announced and pre-ordered it from Best Buy. I am starting to have my doubts as T-Mobile is just releasing devices left and right (SK4G, G2x, G-Slate, upcoming HTC Sensation, Doubleshot, BB Curve Touch,BB Monza, etc.) and Sprint is holding on to the NS4G like its a lifeline.
I feel this 'keeping everyone in the dark' strategy might just backfire. Sprint customers may have no choice (besides waiting for the Evo3D) but I am free to stay with T-Mobile or jump to another carrier if I run out of patience. I hope that won't be the case :-!
