I'm having a reoccurring issue buffering video via youtube and Netflix while on 3G data. I've searched google to no avail. I first had this problem when I jail-broke my iPhone 4. Video played fine on both and then after I jail-broke it would only play for a short period and then stop while buffering and then start again. At times I couldn't even get a youtube video to play.
I upgraded to the 4S and no issues with either until I jail-broke it. Now I'm having the same issue. Trying to watch a video on Netflix and it stops every 20-25 seconds for about 15-20 seconds then starts again for 20-25 seconds. Very frustrating. I realize that watching via Wifi solves the problem but I like to watch video on my breaks at work and we don't have access to the company Wifi.
I don't know if anyone has any ideas, tips, or tweaks as to what I can do to help with the buffering of video on 3G data. I do have 3G Unrestrictor and I've tried it both using 3G Unrestrictor and without as well as turning Wifi off thinking it might be conflicting.
