Cyber squatter fears
The so-called land rush has also raised fears over cyber squatters registering lucrative domain names.
Jonathan Robinson, chief operating officer of domain name firm NetNames, said: "The threat to brand owners is as serious as with any other major domain launch.
"Any organisation which has yet to secure its dotmobi trademarks has left itself wide open to abuse from cyber squatters, domain name speculators and competitors."
Mr Edwards said he did expect some cyber squatters to register names during the registration process.
"The attractiveness of dotmobi names to cyber squatters is, I believe, far less than dotcom," he said.
