Replying to: Building a cell phone. by mright123
In reality, if it works, no one's going to come arrest you. No one would know. If you built a GSM phone your carrier probably wouldn't even know, depending on how they treat IMEI numbers.
If you were a very skilled electrical engineer, you could probably build a working phone using a reference design kit as a starting point, for as little as a few thousand dollars.
But it would be a massive thing that wouldn't come close to fitting in your pocket. To build something anywhere near as small as a real phone, you can expect to pay around $50,000 to have a company with the right equipment build you a real, working prototype of a typical phone.
