I tried to illustrate a logo using no mobile phones, because the brief specified no phones please, models are constantly changing etc. Instead, I came up with the idea of illustrating the initials: M.D. (mobildelar.se) shaped very angular, trying to make the initials look like a Printed Circuit Board, or PCBs.

In electronics, printed circuit boards, or PCBs, are used to mechanically support and electrically connect electronic components, including mobile phones, therefore, I thought this might present a different approach to designing a logo for Mobildelar, rather than, illustrating a mobile phone, keypad, or radio signals to deliver the overall concept.

In addition, I illustrated my version of a particular Screwdriver, which may be used in the industry for repairing mobile phones etc. The (Torx) T6 Mobile Phone Screwdriver, for opening Nokia and other models.
Bearing in mind, Mobildelar is selling cell phone housings, mobile parts accessories, tools, spare parts, Bluetooth, headsets, memory cards to mobile phones, therefore they may also offer repairs etc.
