Follow along with the video below to see how to install our site as a web app on your home screen.
Note: This feature may not be available in some browsers.
Firmware download is limited to 1 firmware per day & computer
EDIT:
actually i think it is actually the leaked one that someone was using for samsung-firmwares.
oh well i guess theyre gonna be a bit pissed off
this is not made be sephail, sephail made fus downloader.I don't think it is.
Firstly, it is the same developer, who made FUS Dowloader.
Secondly, it only has access to publicly available servers, where NPS gets the updates for eligible phones.
Thirdly, SF's app looked differently on their screenshots (at least as I recall...)
browsing the list though it looks like all the current 1.6 versions are now officially on FUS
If that's true, we will be getting 2.6.29 sources soon!
agreedGood point!
Okay then, enough arguing about the source of the app, let's get some popcorn and wait )
JD1 and JD2 firmwares are available but it looks like they're for i7500L. The software is buggy so I can't download it.
GT-i7500LI7500LZVVJD2I7500LVIJD2I7500LVIJD2_ZVV.zip
This should be it.
People (well, so far only one person) at 4pda.ru say they can't get update through NPS, and the latest reported version is still I7500XEII5.
Why would they still be working on 1.5 firmwares anyway?
For all it's worth, I think it's safe to say it is more likely we'll get a 1.1 update than a 2.1 update (official ofcourse). 
Could someone please mirror this software? I don't really feel like registering @ MoDaCo just to obtain this program...
InFect?
