First I will say that windows 8 is AMAZING. I had the Nokia Lumia 920 and likes a lot of the personalization features but it lacked my Pandora, pinterest, myfitnesspal, Spotify, and other apps I use daily so I went back to IPhone.NOW, Onto the Lumia 1520. I  had the IPhone 4S. I liked a lot about my iphone but was bored. Seems like since Steve Jobs passing...theres nothing awing about new phones 5, 5c and 5s. Same ol Same ol EXCEPT now...a lot of my apps are always crashing. My wifi isn''t that strong in my room, my front camera quit...and it''s almost the same as the first iPhone. A lot of good changes but not very many customization features for me. Plus with apple products...EVERYTHING costs.BEFORE PURCHASE:  I decided to get Nokia Lumia 1520 BECAUSE1. Supposedly had many of the apps that I previously could not get on my old Nokia2. More customization with Windows 83. Beautiful Big Screen Like a Tablet4. Amazing Camera by Carl Zeiss5. Mostly...Side by Side comparison that I did with IPhone 5c, 5s and Lumia 1020.(if you can do this side by side comparison which I did on AT&T...I would do it because it answers a lot of questions and made my decision 100%)6. Ability to Expand storage with the miniSD port7. Ability to get phone in yellow. It was a hard decision between yellow and red because they are both beautifully vibrant but I went with yellow because I love the brighter.UNBOXING:Amazed by color brightness, screen brightness, size and beautiful camera.In the first few days I learned a few more awesome things1. the Lumia now does SnapShot and if you are or have been an iPhone user this is awesome.2. There is a driving mode you can set up with a Bluetooth device to avoid wrecks. No touching phone while driving.3. Some of the apps that were previously said not to be on the windows phones were now there. In face the only thing I do not have that I used a lot was weight watchers...they just have a rinkidink calculator but im sure that will update.4. I can trim videos.5. The live tiles are awesome.Apps that I use a lot that are available that on some reviews were said not to bePinterestSpotifyRdioInstagramAmazonAllrecipesNetflixPandoraMyFitnessPalApp folder (to organize all your apps like IPhone)FREE RINGTONES...NO MORE PAYING FOR THAT CRAPKidsCornerWallet to store credit cardsRun the MapRuntasticVineYouTubeHDI have had this less than a week so I know I will learn more and I will rereview or add to it but my current Conclusion isIf you are looking to upgrade and thinking about trying something new...better camera...more customization with out sacrificing simplicity...live tiles...mostly free apps...free ringtones...driving mode...no sacrificing your current apps, free office, ability to back up on skydrive and at&t locker....find your phone...ANNNND SOOO MUCH MORE...SWITCH! You wont regret it.Things to know:1. This phone is huge...6 inches. I LOVE IT...some do not. I can see everything beautifully.2. Get a CASE! SERIOUSLY This phone is very slippery on the back. You need some kind of protection and grip to prevent dropping it or if you do to help protect from the fall. *Be carefully applying tight cases...do not press hard on display screen because you can easily distort color on display screen*3. GET A SCREEN PROTECTOR...I recommend armor brand. They have lifetime warranty and less than 10 bucks with amazon free prime shipping.4. If you want smaller phone..you might try Nokia Lumia 1020...better camera and smaller but lacks some of the specs 1520 has. Do side by side comparison.
