Q. I have an iPhone 4 and wish to upgrade to the iOS 7. Shall I go ahead with it?
Rajkumar Menon, on email
G&G: Technically, the iPhone 4 will officially support the iOS 7 update. While we will recommend you to update your phone to access most of the apps (that will be updated for the iOS 7 soon), you will not get access to the features that are hardware driven and meant for the iPhone 5S. Also, do keep in mind that the OS update might slow down your phone a bit and drain the battery much faster. You can go back to earlier software from http://www.ipswdownloader.com/.
Q. I am planning to buy a good Android smartphone with a superb camera. I am confused between the Sony Xperia Z and Samsung Galaxy S4. Which one should I buy?

G&G: Both the Sony Xperia Z and Samsung Galaxy S4 have got great cameras. Sony has an edge over the Galaxy S4 as it is a water resistant phone and is sturdy. Also, if you are serious about imaging, you can check the Samsung Galaxy S4 Zoom that comes with a 16MP camera and a 10X optical zoom. It is undoubtedly one of the best camera phones in the market today.
Q. I want to buy an iPad and need to understand why having a SIM slot is important in a tablet. Kindly revert as it will help me decide which tablet to buy.

G&G: Apple iPad is available in different storage capacities in two variants - Wi-Fi and Wi-Fi + 3G. The difference between the two is that you need to always stay in a Wi-Fi enabled zone to access Internet on the tablet. Whereas, on the latter, other than Wi-Fi you can also access internet through a 3G SIM. This gives you the freedom to access almost everything on the move.
