I have, for the last 2 weeks, been switching back and forth between a first gen iPhone running 1.1.4 and a 3G running 2.1 and have noticed that the 3G is significantly choppier and slower (UI) than 1.1.4. I've timed a few functions: 3G "settings" takes between 6 and 8 seconds to load. 1.1.4 takes about about 1.5 seconds 3G "SMS" takes between 4 and 7 seconds to load. 1.1.4 takes about 1.4 to 1.6 seconds to load 3G "Photos" takes about 4 seconds to load 1.1.4 takes about 1.5 seconds to load Both phones have the same content on them. Also, scrolling through photos on 3G is choppy where the 1.1.4 phone is perfectly smooth. Quick changes between functions (for example going from "settings" to "mail") tends to choke the 2.1 phone whereas the 1.1.4 has no slowdown. Can anyone report similar times on their 3G with 2.1 or does it seem quick and responsive? Comparing the two (at least in my case) the 1.1.4 phone is so much more responsive and instantaneous but the 2.1 seems bogged down. I'd really love to hear if other people are experiencing similar load times on their 3G. Thanks in advance for the input!
