I bought one back in late November after T-day for $299 (they were $369 at the time). While I liked ICS (big improvement over Gingerbread) my phone had terrible reception problems, especially with the wifi antenna. I worked with Boost and Samsung tech support to try and get it resolved, but tin the end they both admitted that these are know issues with the S2 and probably not just a problem with my phone. I returned it to Best Buy.
Now that I'm tuned into phone flashing, I would never buy a S2 for $299 when you can get a like-new S3 for the same money and then pay someone to flash it to Boost for you. That's always been one of the big downsides to prepaid--the phone selection usually sucks. But now you can buy any CDMA phone you want and just have it flashed to Boost.
