Pretty Good Internet Device!

I recently upgraded my cellphone from an HTC Magic/T-Mobile MyTouch 3G (<salesman voice>Oh, you still have "that" (:roll: POS :roll:)?? phone</salesman voice> to a Samsung Galaxy III.

Anyway, I kept the POS phone because I liked the games that I had on it plus, everything still worked except that, you cannot make or receive phone calls: Hook it up to Wi-Fi and you can do just about everything you could do while paying the cell company. I can even SKYPE over Wi-Fi to the internet and make calls to landlines.

The GPS / Navigation, email, Android Market and, updates works even; they offered my $12.00 bucks at the mall at a "We Buy Used Phones" kiosks at the mall!

.....errr, I don't think so.

I do the same with my old LG Android phone. Navigation only works when you are connected to the WiFi.... still it works great for everything else. I'm going to have to try Skype.....

Still use my iPhone 3G as a music player. Kind of slow as an Internet device now that I've been spoiled by my 4S.

I forgot to mention the music player and Kindle App for book reading.

Speaking of 4G.....

One network claims to have the fastest "4g" while, another shows charts claiming to have the most "4g" Towers accross the nation. These guys are comparing apples to oranges since they are using different protocols.

In March 2008, the International Telecommunications Union-Radio communications sector (https://forums.hamisland.net/wiki/ITU-R) (ITU-R) specified a set of requirements for 4G standards, named the International Mobile Telecommunications Advanced (https://forums.hamisland.net/wiki/IMT_Advanced) (IMT-Advanced) specification, setting peak speed requirements for 4G service at 100 megabits per second (https://forums.hamisland.net/wiki/Megabits_per_second) (Mbit/s) for high mobility communication (such as from trains and cars) and 1 gigabit per second (https://forums.hamisland.net/wiki/Gigabit_per_second) (Gbit/s) for low mobility communication (such as pedestrians and stationary users).[4] (https://forums.hamisland.net/#cite_note-3)
Since the above mentioned first-release versions of Mobile WiMAX (https://forums.hamisland.net/wiki/Mobile_WiMAX) and LTE (https://forums.hamisland.net/wiki/Long_Term_Evolution) support much less than 1 Gbit/s peak bit rate, they are not fully IMT-Advanced compliant, but are often branded 4G by service providers. On December 6, 2010, ITU-R recognized that these two technologies, as well as other beyond-3G technologies that do not fulfill the IMT-Advanced requirements, could nevertheless be considered "4G", provided they represent forerunners to IMT-Advanced compliant versions and "a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed".[5] (https://forums.hamisland.net/#cite_note-ITUSeminar-4)
Mobile WiMAX Release 2 (https://forums.hamisland.net/wiki/Mobile_WiMAX_Release_2) (also known as WirelessMAN-Advanced or IEEE 802.16m') and LTE Advanced (https://forums.hamisland.net/wiki/LTE_Advanced) (LTE-A) are IMT-Advanced compliant backwards compatible versions of the above two systems, standardized during the spring 2011,[citation needed (https://forums.hamisland.net/wiki/Wikipedia:Citation_needed)] and promising peak bit rates in the order of 1 Gbit/s. Services are expected in 2013.[6] (https://forums.hamisland.net/#cite_note-5)
As opposed to earlier generations, a 4G system does not support traditional circuit-switched (https://forums.hamisland.net/wiki/Circuit-switched) telephony service, but all-Internet Protocol (https://forums.hamisland.net/wiki/Internet_Protocol) (IP) based communication such as IP telephony (https://forums.hamisland.net/wiki/IP_telephony). As seen below, the spread spectrum (https://forums.hamisland.net/wiki/Spread_spectrum) radio technology used in 3G systems, is abandoned in all 4G candidate systems and replaced by OFDMA (https://forums.hamisland.net/wiki/OFDMA) multi-carrier (https://forums.hamisland.net/wiki/Multi-carrier) transmission and other frequency-domain equalization (https://forums.hamisland.net/wiki/Single-carrier_FDMA) (FDE) schemes, making it possible to transfer very high bit rates despite extensive multi-path radio propagation (https://forums.hamisland.net/wiki/Multipath_propagation) (echoes). The peak bit rate is further improved by smart antenna (https://forums.hamisland.net/wiki/Smart_antenna) arrays for multiple-input multiple-output (https://forums.hamisland.net/wiki/MIMO) (MIMO) communications.
