[Q_Q]

Not to be off topic but this is why I see 4G as a definite upgrade.
My 3G data speed is all over the place all over the place also.
So based on the comments here, it appears to me that they've patched together & maxed out all they can on the 3g pipe without consistent end results.

Now, it could be just some network issues but I tend to think that moving ppl off of 3g onto 4g alleviates some of the bottenecks & would improve speed.
