I dont know if/when i'll be able to fish up the us4g or eu wifi ones as the 506/507 ones were named very stupidly. I didnt find the original 514 us wifi one but i did find the eu 3g one.
Keep in mind that this version may be techincally a leak, it was built on dec 19th and shouldnt be released till next week or so under their normal schedule (this is also completely ignoring the fact that the past few weeks have been holiday weeks).
If 514 really hits OTA it may not be till the end of the month
