2.0 3G speed: It would even reach around 2mbp/s on 2.0 sometimes, depending on the area. 2.1 3G speed: Is anyone else getting much slower 3G speeds after updating to 2.1? There's definitely a noticeable difference when doing anything that requires data... Maybe a restore would fix the problem? The only problem is that I have Netshare, which I didn't buy since it was taken off too quickly, will iTunes remove that from my iPhone when I restore the backup? It isn't in my applications since it won't sync back.
