When can something be locked yet still be open?
When it's a mobile handset sold by a wireless carrier concerned about security and bandwidth issues, whose platform was built by an group dedicated to open compute systems.
In locking the G1 to its 3G network, via monthly voice and data plan subscriptions ranging from $25 to $35, T-Mobile has control over what applications will be available to users.
And its the level of control, according to experts, that advances the handset's allure and could also pose some challenges.
While the open platform allows third-party development T-Mobile has locked the device from other networks. The approach is typical with carrier-subsidized handsets -- and the prime element in keeping device price points low. The G1's initial price is $179 with a two-year data subscription plan. Carriers traditionally want control over application use to avoid network security issues as well as bandwidth issues.
Research firm Strategy Analytics estimates that nine out of 10 GSM/CDMA handsets sold in the US this year will be SIM-locked.
Android was built under the auspices of the Open Handset Alliance, which has said the platform will come under one of the "most progressive, developer-friendly open source licenses" to provide significant freedom and flexibility for product design. Google, which acquired Android in 2005, (NASDAQ: GOOG) announced its mobile phone plans in November 2007.
One industry expert, who called the G1 a "compelling story," said the device illustrates that today's "mobile phone is the new PC" and "everything is open right now."
"The message is that the open platform is being embraced and the mobile world just got a little more interesting," Michael Gartenberg, vice president of mobile strategy, Mediabistro, told InternetNews.com. (Mediabistro and InternetNews.com are owned by the same parent company, Jupitermedia Corp.)
For example T-Mobile will not restrict applications providing a work-around to the SIM lock feature or prohibit Voice over Internet Protocol (VoIP) software, such as Skype applications, that come from the Android development community, according to Gartenberg.
"T-Mobile's CTO [Cole Brodman, who also serves as chief innovation officer for T-Mobile USA] told me that he while he can't say he'd like that to happen he isn't going to restrict it or stop it," said Gartenberg. "That's the spirit of how open they are to being an open platform and the fact they understand what it's all about."
According to Gartenberg, T-Mobile will let users unlock devices after 90 days and in case of needing local SIM cards for international travel.
