So someone got their hands on the UK 1.5 image and you can manually update to Android 1.5 Cupcake without having to root your phone and worry about bricking it.
I cleaned up the instructions a bit, because the grammar was horrible. I also uploaded to a third mirror and PirateBay, since RapidShare wouldn’t let me download and SendSpace was throttling the download. If you can mirror this somewhere else, please share the bandwidth and drop a link in the comments. But here you go, from the t-mobile.com forums:
Download the image:
http://rapidshare.com/files/234560998/update.zip.html – Mirror 1
http://www.sendspace.com/file/amcvxn – Mirror 2
http://uploading.com/files/2GDTJMY3/update.zip.html – Mirror 3
http://thepiratebay.org/torrent/4906690 – TPB Torrent
Download one of these and copy to your MicroSD card.
1)Turn your phone off. Boot while holding the home button.
2)When you see the triangle, hit Alt+L
3)Then Alt+S
4)Press Home and Back when it tells you to (to reboot your phone)
5)You’ll notice it says installing Radio after you hit Home+Back (thats normal and fine)
6)You’ll see it reboot like 2 times then you’ll see the new android loading screen. and there ya go! android 1.5 without having to root/jailbreak and you’re good to go.
7)when 1.5 for the US comes out, just repeat the same process except with the TMobile USA update.zip
Please note, just like the JF1.5 image and others currently out, this does not include the IM application, only Google Talk. It’s also reported that Amazon MP3 and Google Voice Search are not included.
