Just letting people know the following:
I know a few people that have a Z10 most are unlocked imported units using stl100/1 and stl100/3 usually running either 10.1.0.4181 or 10.2.1.424 who want the 1925
I spoke to my contact at digicel/blackberry and he tells me that 1925 will only be "pushed" to Digicel handsets and that owners of imported units will have to go to Kingston (our nation's capitol- I am in Montego-Bay 3hrs drive away) office to see if they can get it AND it has to be done via USB - I have given him my email and he is sending me a link for the10.2.1.1925. He says it is a 2Gig file.
With the following caveat, do a back up first, and it is only recommended for STL100/1 units.
Apparently once the file is downloaded you plug your phone in and it does the rest, I am unfamiliar with side loading, and such etc and am just repeating what he has told me, I will then give the link to other Z10 users here with the caveat of course.
Regards David
Z10 / 10.2.1.537
