I dont understand what you mean.
Sony Ericsson make their phones with their own User Interface, and features. The design of the phone allows phone operators like Vodafone to come and customise it with their stuff.
That doesnt overly worry me (well apart from the hideous icons and colour scheme that VF use, ruins the SE interface). What bothers me is how Vodafone disable features on the phones or only make certain things usable if you purchase them off the VF Live site, MP3 as ring tones springs to mind (in that you cant use any MP3 file as a ring tone on a VF Live K700 only Vodafone sanctioned ones, unbranded K700s allow you to use ANY MP3 file, basically its a moneymaking exercise).
If its Vodafone thats crippling the phones then it should be them we are complaining to, not Sony Ericsson.
Personally if I pay good money for a phone, I want the phone to do all that its supposed to do, not have a phone operator dictate the terms (not counting network specific functions).
PS....you should visit some of the mobilephone forums, ESATO, MOBILE REVIEW.COM, MOBILEBURN etv and you will see there are ALOT of people unhappy with Vodafone Live.
