To explain what an unlocked cell phone is, it may be better to describe a "locked" cell phone. Normally, when you purchase a cellular phone and a particular plan for that phone – through service providers like Cingular, Sprint, Verizon, and T-Mobile – your cell phone will remain "locked" within their network. If you try to change carriers for your cellular phone service, your particular cell phone will not work. So, someone using Cingular who wishes to change plans and become a T-Mobile customer will also have to purchase a brand new phone.
Cell phone service providers have been competing aggressively for years and trying to tempt other company's customers to their network with cheaper plans and more "free" minutes. Before unlocked cell phones, this was a huge hassle. Not only did you have to buy a new phone when you changed cellular services, but you had to replace a fully-functional phone!
Most U.S. service providers for cellular service work off of individual networks, so when you go to transfer your service and change your phone, it can be a big challenge. Well, that is…up until recently! An unlocked cell phone gives you a lot more freedom of choice in your cellular service provider. When you have an unlocked cell phone, you can switch providers without the need for purchasing a whole new phone!
Thank goodness you can now buy an unlocked cell phone! This opens up so many possibilities when you go to buy cellular service. If you don't like one service provider, you can switch providers (once your service agreement has been completed) and keep the same cell phone, complete with your phone book and all other programmed extras.
In some cases, when you didn't buy an unlocked cell phone to start, you can have your current carrier unlock your cell phone. Just call the customer service department of your current carrier and ask if they would be willing to unlock the cell phone you have with them.
Buying a GSM unlocked cell phone would be a good investment if you have any future plans to travel overseas. GSM, which means Global System for Mobile Communications, will give you the knowledge that your cell phone will work with overseas networks.
Having an unlocked cell phone is much more convenient when you go to change carriers. An unlocked cell phone allows you to insert any kind of SIM card, or Subscriber Identity Module, into the cell phone. Then, that phone will be able to pick up local network service....

[+/-] : Acer Gemstone Blue 6920 and 8920 various
Two entirely new screen sizes 16inch and 18.4inch, these are so the 16:10 ratio on earlier offerings can be changed to suit the current DVD's and TV that want 16:9. All have variety of NVIDIA graphics cards with 512MB of RAM plus extra shared RAM.
The prices are expected to range from £699 to £1399. I noted what I could from a very busy PowerPoint presentation. Just as well I did as the slides were not on the CD so I can only quote the main points.
Most of the new offerings come with Blu-Ray drives and some come with two hard discs. The 18.4inch offerings come with five speakers and sub woofers and while the 16inch also have simulated surround sound. Output from headphones will be simulated surround sound in both panel sizes. I look forward to reviewing the Dolby software built into the motherboard to give true surround sound from the five speakers when I manage to get to review one of the 18.4inch offerings.
Other enhanced features over the models they replace include 250-nit brightness (up from 200-nit) and colour gambit of 60% (up from 45%) for the 16.4inch models.
On the software side there is the Media Console featuring Acer Arcade Plus giving rapid control over both sound and video. All come with Vista, some with Ultimate the rest with Home Premium. Other software is supplied including a variety of trials....
