As the title sublimely hints I recently received an N73 on Three... student deal, worth it, so I thought.
The phone is great. I say this having used an N70 for 12 months. I knew what I was letting myself in for. Again... so I thought.
Turns out that Three (as with most network providers) like to have their own branded (and locked) version of the OS, which is fair enough. The only problem with this is, it seems Three's firmware is complete and utter crap.
It's not crap because of the custom menus. It's not crap because of the Three lock-in. It's crap because it won't let the phone turn off in any profile other than "General" and it crashes all the time. I'm not the only one with this problem, either.
Sorry, I meant to say I wasn't the only one with this problem. Thanks to the wonders of the Internet, I found a list of product IDs for the N73, including IDs for Vanilla variants of the phone.
Using a tool called Nemesis Service Suite I wrote a new PID to the phone (vanilla N73 Music Edition, Euro 1 as it happens). Then, I ran the Nokia Software Updater, which updated the firmware to the latest vanilla N73 Music Edition Euro 1 version.
Long story short, now the phone actually works properly and it has a proper mp3 player. Oh, and no dodgy Three animiations either.
This procedure's supposed to be a bit on the risky side, so I tried it first on my old Vodafone branded N70 to prove it worked, then did it on my N73.
Not something I'd recommend to others... I'd say the N73 is great, but stay away from Three!
