SonyEricsson K750i on Vodafone

SonyEricsson kt50i Vodafone brandedThe good news is that the new SonyEricsson 2 mega pixel handset is available on Vodafone UK. The bad news is that it is heavily Vodafone Live! branded and has limited functionality compared to a standard SE handset.
1. Vodafone has disabled MP3 ring tones.
2. The user interface is different from the SE original. Buttons have been reassigned, menu icons are Vodafone versions (uglier) and have different positions.
3. Vodafone logo on bottom of phone, Vodafone button above joystick.
4. This “special” edition handset is in silver (brushed metal) unlike the standard black.
5. Vodafone Live! is accessible from at least 5 different points (buttons and menu options).
Orange has also branded the K750i. While the branding is not as heavy as the Vodafone one, the icons have been replaced with low quality version.
O2 is currently the least branded k750i, unless you get a SIM free version.
Some of these issues can be remedied. To be able to play MP3 tones, MP3s can be altered with the SonyEricsson DRM (digital rights management) packager. The packager will add the digital rights in a quick step (less then 5 seconds/ song). The files will get the dm file extension and can be used on the Vodafone Live! branded K750i as ringtones.

After using the phone for a couple of days I find the features of the phone to outweigh the Vodafone branding so I can still recommend it, especially if it is a “free” upgrade.
The 2 MP camera is very good for a mobile phone. Maximum resolution is 1632×1224 pixels. Auto focus has been added which lets you focus on certain items by pressing down the shutter button half-way. Macro mode actually works and a light has been added to be able to take pictures in dark environments.
The phone records decent mp4 video clips as well. All can be stored a Memory Stick Pro Duo (that’s a mouthful) card which nowadays are available up to 2 GB.
Please use the Vodafone branded SonyEricsson K750i forum to post any questions.
Update 05/01/06
Just a note that I have successfully flashed my SonyEricsson k750i with the R1AA008 non-Vodafone firmware using the standard USB cable and the DaVinci Team software.
Total Vodafone debranding. The standard SE icons are much nicer. The middle button functionality is restored. Can use mp3s as ringtones. No “risk” of accidentally connecting to Vodafone Live. No annoying game demos were included. A few fully functional games and apps were included. I even chose a language combination that includes Swedish so that I can use Swedish T9.
Highly recommended!

Unlocking your mobile phone for free

Our lovely mobile networks have for the last 2-3 year been locking mobile phones provided by them. The “network lock” renders the mobile phone unusable when a SIM card from a different network provider is inserted. Using multiple SIM cards is especially handy when abroad because using a SIM from a local network is so much cheaper that roaming.
When you sign up for a mobile service contract (as opposed to Pay As You Go, PAYG), the network often gives you the chance to purchase a heavily subsidies phone.
I can understand that the operator wants to recuperate the cost of the phone but to keep recuperating that costs indefinitely I think is uncalled for.
There are “unofficial” methods to unlock your SonyEricsson phone but they cost, will most likely void any warranty and may in rare cases damage your phone. Nokia phone owners are more fortunate as Nokia phones can be unlocked without the need for any hardware and there are even sites that provide Nokia unlocking codes for free.

Instead I wanted to pursue a free and more civilised approach and thus decided to contact my Vodafone customer support and start arguing.
During the last 3 days I have been given several answers from Vodafone customer service:

  1. It cannot be done
  2. We do it because all other networks do it
  3. We have to contact the manufacturer (SonyEricsson), it will take weeks and cost you £30
  4. Just pop into a Vodafone shop and they will do it for you for £15
  5. Of course sir, your contract has expired and as such you have the full rights to your mobile phone. Here is the unlocking code

It was the customer support responsible for “Using your phone abroad” that was finally able to help. I recommend you to navigate (via the multiple choices phone system maze) to them if you are at the end of your contract and would like to reclaim your mobile phone.

Regarding the other UK operators such as T-mobile, Orange and O2 (BT) and I can only hope that they are reasonable enough.
The whole mobile phone locking reeks of anti-competitive practises that might possibly be contested with EU laws but nobody has chosen to take a mobile operator to court for those £15-£30.
Huzah, another consumer victory!
