My problem with 4G is there is no handshake between the 3g and 4g radios meaning when I'm in spotty coverage (most places), and it switches from 4g back to 3g, it cuts your data connection completely for a few seconds. Same when it's switching from 3G to 4G. I use Gtalk
A LOT, I have Gtalk messages coming in all the time. Gtalk uses data connection. So to my friends it's appears that I'm online, I'm offline, I'm online, I'm offline. It's confusing and frustrating for them because they don't know if I'm truly offline or not.
I don't think it's possible for this to be corrected due to the EVDO/1xrtt and Wimax radios being separate radios so I'll likely never turn on 4G until it blankets me in its fast speeds as well as 3G does
Probably not a big deal for some but i rely on my phone so i cant have constant data connection drops.
