T-Mobile 1900MHZ HSPA(+)

     For a while now T-Mobile has running their new 1900 MHZ network to target AT&T users because all new devices have the 1900 MHZ PCS band so T-Mobile can give HSPA service to devices without the 1700/2100 MHZ bands.

   T-Mobile has been covering Washington DC with 1900 MHZ since the day it was launched and yes did I get excellent speeds with the compromise of coverage, meaning that due to lack of coverage 1900 MHZ can reach my speeds were lowered to EDGE in buildings and received numerous dropped calls. But, let's look at the history behind 1900 MHZ, the band was originally used by AT&T (still is today) to provide GSM/UMTS to their customers so this band is the reason why AT&T earned it's reputation back then as having the spottiest coverage in the US. So to keep it's customers AT&T did a 850 MHZ refarm, similar to what T-Mobile is doing but T-Mobile is doing this at a slower rate due to not having the money to deploy spectrum in every market. But if you would still like to try out T-Mobile's 1900 MHZ network you can do so for less than 40 dollars and use this as an on demand service or use it for primary uses.
 
  If you would still like to test out T-Mobile's new 1900 MHZ network I'd recommend using a device like the Nexus 4 or a device with 1700/2100 MHZ bands as T-Mobile non 1900 MHZ network is AWS so you need both 1700/2100 MHZ bands to get T-Mobile HSPA when not covered by 1900 MHZ. But if you live in an LTE market, I'm pretty sure the super fast LTE speeds will compensate for the lack of 1900 MHZ coverage.

What iWant for iOS 7/iPhone 5S

     Right now iOS 7 is in beta stage and I have tested out a few webapps that I've made and they work flawlessly but that's besides the point. iOS 7 right now all I think about it as just eye candy I like all of the icons but I feel that iOS 7 is missing somethings. I know iOS 7 is in beta....

1.  NFC support for the iPhone 5S and maybe a case or dongle to allow NFC support for the previous iPhones.
2. AirDrop for all iPhones and iPads. Apple is notorious for leaving out features in newer iOS versions for only new iOS devices. Can't say the same thing about any Nexus.
3. A debugging bridge to issue out root commands or get a logcat to diagnose the problems.
4. Faster and more fluid transitions on iOS 7. Seriously Apple the transitions take WAY to long and need to be more fluid.
5. At least a quad core CPU if Apple can do it make your own CPU but I want to go with what I know is good but doesn't exist A S4 PRO CPU & PowerVR SGX 544MP GPU. That will murder the benchmarks.
6. Category 4 LTE equipment to boost LTE speeds past 100Mbps.
7. Native Hardware acceleration in the SpringBoard and maybe in applications. (Sorry Devs :( )

Why Tegra 3 OC isn't needed

  Sorry viewers :( I abandoned my blog after less than 6 months of usage however, I haven't realized the important message the blog has had and it's own importance to me in spreading the word about things that some may say meh it doesn't matter or things like WOW that simply rocks.

      So, many devices like HTC's previous flagship the ONE X (Endeavor) or Google's own Nexus 7 feature the Tegra 3 chipset and I feel that it simply doesn't need to be overclocked. For example, we can overclock the Nexus 7 up to 1.7GHZ yet, to see our benchmark scores go up a few FPS or shave .001 of a second from app launches but honestly I feel it's just not needed for a Quad core CPU and 12 GPU to be overclocked due to many risk that not only affect warranty (Thanks HTC) and long term usage.
   
       Many devices with Tegra 3 are throttled when heat levels exceed a certain temperature and the device begins throttling it's self to maybe 800 MHZ and/or taking some CPU cores offline to protect from heat damage. There is a solution to this called undervolting, however undervolting can cause long term usage problems and short terms problems that can be fixed with a simple battery pull. For example my old Samsung Captivate when it's undervolted when running @ 800 MHZ it simply crashes but a much higher frequency 1.5 GHZ uses when undervolted has to use less power due to what I believe is caused by the die on the CPU meaning that my phone will crash when undervolting @800MHZ but not at 1.5GHZ no matter how high or low my MV is.
