ups.. the e680i is slower than a780 BUT the org e680(not i/g) is nearly same fast than a780.
the e680 FW is an older one, the e680i/g FW and the a780 FW is quite same..
why is that difference between the a780 and e680i?
here JBenchmark 2.0 list
http://www.jbenchmark.com/result.jsp?benchmark=v2
the a780 as the fastest linux phone, than e680(not i/g),a910, a768/i, than far far behind the e680i/g on the 4th page!
the fastest phone from the whole list is the Samsung SGH-i607 at moment.
