Conte para a gente quem é você e quem é seu público alvo
18 - 35 year olds shopping for a mobile phone online.
The logo needs to be fun, friendly, modern (web 2.0ish), unique (most important), clear... but not cheesy!
I would like to build a brand so maybe the use of a cartoon character, it doesn't have to be a walking mobile phone, but not ruling that out! This is only an idea, your design does not have to include this.
If you want to drop the "UK" please feel free, I'm not sure if I want it in the logo
