iPhone/iPod Touch/iPad iPhone: 1G, 2G, 3G, 3GS, 4 iPod Touch: 1G, 2G, 3G iPad
1G is based on frequency modulation,analog technology,TDMA 2G is based on digital technology,FDMA 3G is based on CDMA which is a faster internet access source
When they say its a 2g phone it means its a 2nd generation phone. Just like 1g 3g and 4g
Sadly, no i tried to use 3g or 1g firmware on my ipod touch 2g and it didn't work. You have to have the exact firmware file. Like if you have an ipod touch 1g with 2.2.1 firmware you have to have the file made for a 1g itouch that has 2.2.1 firmware
1G is flat 2G is horizontal 3G is vertical 4G is overhead 5G is pipe
2g is 2nd generation 3g is 3rd generation
The iPhone 2G is much slower than the iPhone 3G.
1g is slowest 2g is medium 3g is good 4G is the best.... so..... 4G
3g BTS is greater than 2g bts. and it is with new technologies.
1g is slowest 2g is medium 3g is good 4G is the best.... so..... 4G
i say $150(1g) $225(2g) $280(3g) $340(4g)
2g is 2nd generation 3g is 3rd generation. 3g is much faster. iPhone 3G can support WCDMA and HSDPA frequencies, but the iPhone can't.
