I am considering upgrading my Prevail to either an S2 or a Design 4g. While I understand that the S2 is superior to the HTC in almost every way as far as hardware goes, the almost might be a big almost. From what I've read, the S2 does well in all departments except cell/GPS/3g/4g reception. While all those other features are great, the core reason for having a phone like this would be to make use of its ability to make phone calls without constant signal drops or use the internet or GPS reliably when not near Wi-Fi. So I am curious for those who have experience with both (obviously not a Boost version of the S2 since it isn't out yet) about their thoughts on the actual signal between the two. Also for those without the experience, what are your thoughts on this? I'm also wondering if you can do a hardware mod to the phone to improve signal strength?
