Actually the unit I purchased has an update installed. So far there are 6 out of 7 satellites locked in consistently. GPS was a primary concern of mine as I was fully aware of the issues. Battery life isn't very good, but at least I have a spare. I got a half a day per battery today, my first 24 hours of actual use. I bought a 32GB SanDisk MicroSDHC that should arrive by Friday. I got it from Verizon Wireless for $99 with free shipping. The list price is $199. (A few months ago Verizon sold them for $50.)

Also there is a Samsung utility, Kies, that is a must have, but not normally available in the USA. One just has to tell the server they are in the UK.
