A lot of active research and development into mobile phone technology has been underway:
Operators are upgrading their networks to advanced wireless and other third-generation (3G) services, many new entertainment and communications services are becoming available, including new broadcast-type operations on spectrum formerly occupied by Television channels 52-69. With downlink speeds close to that of wireline DSL, mobile service can now provide music download and streaming video sharing. Services such as MobiTV or Juice Caster are some applications that leverage these new networks.
Development in miniaturized hard disks and flash drives to solve the storage space issue are already surfacing, therefore opening the possibility for phones to become portable music libraries and players similar to an iPod.
Some cell phones already have GPS positioning. In the future, this may be coupled with accelerometer positioning, to cover underground or indoor positioning. This would lead to maps and help finding group members nearby, or identifying strangers. When coupled with camera phone, the GPS technology may also allow users to take a picture or snap the exact location and angle at which the picture was taken.
