hi guys! i was planning to trade in my V3 for an E398 because i need a phone with a mem card slot but I''ve tried a few of my friend's E398's and their's all lags really bad, even with just a 256MB card.  I was reading through the forum and i read about the firmware that can eliminate the lag and i'm curious about it.  Does it make a significant difference, eg. songs load faster, pictures come out faster when browsing throught the gallery and i can use memory cards of 512MB or 1GB? and do you guys know anyone through lowyat.net that does it? thanks!
