"Skyrocket vs original GS2"4.0 starson by mrblondny
Pros: Big bright screen, LTE
Cons: Slippery, buttons hard to find, buggy
Summary: Upgrading from an iPhone 3GS, I got an original GS2 but exchanged it once the Skyrocket came out, being totally unimpressed with AT&Ts HSPA+ network speeds. It didn't provide a noticeable boost over 3G. The OGS2 felt better in the hand, was easier to hold due to the textured back and square sides, and the buttons (power & volume) were easier to use. The Skyrocket needs a case badly because it's thin and smooth tapered sides combined with light weight make it hard to grip.
The Skyrocket's screen is slightly larger but 4.5 vs 4.3 is negligible. Battery life seems worse so far despite a higher capacity battery. Careful power management is required of all Samsung phones to get a full day out of them. The physical buttons are too flush and I am always fumbling with the phone to get it right side up.
The Skyrocket has a bug in the battery meter, sometimes getting stuck on 100% until it goes dead. The phone must be powered off to reset the meter. Also the bluetooth toggle fails at times, indicating on but not emitting a signal and it won't pair.
The OGS2's processor is better, with smoother scrolling and quicker screen refreshes, faster app closing etc. There is a definite lag with the Skyrocket at times but not particularly annoying. The Skyrocket would probably be much faster rooted but I'm waiting for ICS before doing that.
I was able to use the Skyrocket in two cities with LTE enabled, Boston and DC. It is quite fast and validated the whole reason I got a Skyrocket. My city has just gone live (supposedly) so my day to day speeds are yet to be determined. An LTE radio toggle would have been nice to save battery. When you are on HSPA the "4G" icon lights up, and "LTE" is displayed just below that when it is available.
The pace of phone releases by AT&T is ridiculous. There is a new flagship Android phone every week. They need to chill and get the network and QC in order instead of just dumping mostly ready devices on a partly ready network.
If you are in an LTE market and crave speed, get the Skyrocket. If it will be ages before AT&T upgrades your area, get the original GS2. It's a better phone except for the radio. IMO both are way better than the iPhone.
