I heard that in Bnei Brak they like iPhones recently, even Rav Chaim Kanievsky is talking about them.
I myself have a Sony (Ericsson) Xperia Arc S, from the 2011 series. Pretty good phone, *with* replaceable battery. I use a lot of power and I use my phone as emergency GPS device when mountaineering and in rough terrain, so I always carry spare batteries. No sense in using a phone with a fixed battery then. (Think iPhone.)
Which galaxy are you referring to? The S3 is great, the Blackberry Bold is practically antique, and I haven’t tried out the i5, but it appears to be the best (it’s thinner, lighter, faster, and more crash-resistant then the S3, has 700,000 apps, no malware, and has a unscratchable sapphire crystal lens cover), and of course, the gedolim assur all of them, although rabbanim seem to think of the BB as being less “dangerous”, for some reason.
