Download locks up when switching from 3G to Wifi

Just a quick observation. I was in the middle of a file download over 3G when my WiFi kicked in and "took over". The download just froze from that point on and wouldn't continue. No biggie...I canceled and restarted it on wifi and it finished, no problem.

So I was just curious if that's normal. If you switch from one to the other in the middle of a file transfer, it seems logical that it could cause things to get a little flaky. Is this by design, or just the nature of the beast?

i havent had it do that on a file download, but if i go from wifi to 3G on my browser it tends to lock up then.

Yes, this probably sounds normal. Are you using the Internet Browser when you switch to Wi-Fi?
