I have a 4s on verizon, which gets about 1mbps at my home. I also have Verizon dsl rated at 3mbps but it bogs down to .70 Mbps at peak times. When ever I try to down load something large like a theme on Cydia and I'm on wifi it downloads just fine at that really slow speed. If I try to download a theme on 3G which is faster that the dsl at that time it downloads at a crawl. It's so bad I can't download at all. Just small tweaks. I don't see what the problem is. Does cydia have a limitation in data speed and sets the limit at how fast you can download with slow 3G? I don't have fios in my area or I would have upgraded already. Thanks.
