We all SGS2 user will experience the same as what you are now....Dual Core technology will create and generate HEAT so it is just normal bro. The technology itself is build for that type of situation, so be no worries.
Just for your information....last few weeks when i'm using the SGS2 (oversea set)....i faced a very rare overheat feeling, and it is toooooooo dammmmmmmmm HOT came out from the phone when the phone itself hung at loading some high end games .....but then i realize that, from my experience with electronic items, sometimes it needs to be stressed up but not too much (a.k.a burntest).
Around 3mins with hang condition after that i decide to kill process and reboot it.....and then you know what, after that incident and till now i experience that my phone is working SUPERBLY HELL SMOOTHS speed and DARN MORE efficient.....thank god for that. And now i'm very2 satisfied with product. 

morning, want to ask, is it worth to buy micro sc card class 10 or just class 4 enuf??

Where got hard to get SGS2 battery?

Original Korean-spec SGS2 battery from ExportPrive for $25. Quick and easy postage, PLUS it lasted me 10 hours straight today (Samsung must have packed some voodoo inside their domestic batteries lol, my inbox battery struggled to get past 8 hours).

Plus you get this (read the small print on the battery, left one):



ENNNN.....EFFFFFFF....CEEEEEE (ANTENNA only lol).

But really, I'm not dissing MugenPower, I SWORE by their Nokia BL4C batteries, which was 1900mah vs the Ori 1500mah, and lasted as long as advertised (ALTHOUGH old timers at XDA/Maemo.org HAVE noted that their batteries lose charge a tad faster then Originals). And from personal use I can say that some MugenPower batteries have "loose contacts syndrome" (their BL4Cs - I had two - DID NOT work with my Nokia N810s UNLESS I wedge a piece of paper in the battery well).

But a 50mah hike for an extra $20. Not this time Mugen, I can get 2 ori batteries with ENNN EFFF CEEE (antenna) for that price lol.

The 3200mah battery on the other hand is an entirely different story. If only people made TPU cases for THAT monster.

Also on ExportPrive:


2000mah double port Samsung charger ($22)


Battery charger/stand ($13) - I'm using this and I can say it's confirmed ori, feels quality as hell.


MHL HDMI adaptor ($33)

Just got the double USB charger and HDMI MHL adapter from them, express shipping. It should be here by the week or the next heh.
