www.sido.com.hk is where they come from.
Ok well my first impression on the batteries is that they tend to take a bit longer to fully charge. I've not had them long enough to determine a full days use.
One thing that happen and has never happen before and might be just coincidence, is that my phone didn't want to "wake up" this morning and I had to soft reset to get it going.
Only 2 things different on my phone from previous days is installing and charging this new battery and switching my PCM keyboard skin and layout to "blueiclone".
