Yeah to escape the cluteches of AT&T and their dropped call and slow net reputation I switched myself and my two kids to Sprint on Sunday (July 10th); got the new Evo 3D for each of us.
WELL... The 3D hurt our eyes and having sprint hurt our heads....LOL Going from where I live (East Side Suburb to Cleveland OH) to where I work (Downtown Cleveland) I would loose internet connectivity 4-5 times. NONE of this is a rural area AT ALL.... I hit 4G in one spot in downtown.
Accessing a YouTube video (RayWilliamJohnson) OF COURSE...

on my Sprint phone using 4 G and a co-worker backing his Vibrant down to 3G; his video started (same video) a full 12 seconds before mine, and played through... Mine stopped to buffer twice.
WHAT A JOKE...
I was back with T-Mobile 9:30 am Tuesday.
Honesly I love T-Mobile, they have been flawless for us.
I swithed because of the merger, and Sprint offered to save me 115.00 per month on the three phone plans..
You get what you pay for and I will never make that mistake again.
I will take my chances with AT&T (I did not go into the no net while on a call thing but man that REALLY sucks - so no Verizon either).
AT&T don't screw us... Offer solid service.
