Android or iPhone App?

The question is not which one is better. But, it's a privacy issue. For the same application, if it have two versions: one for Android platform and one for iPhone or iPod Touch, I will check to see which permission should I grant for an Android app. iPhone, iPod Touch, and iPad does not give me that choice. Since I have no way to know what privilege an iOS application exercise on my mobile device, I will not using the iPhone. My iPod Touch and iPad does not contain any sensitive information like my contact, my phone number, so it's Ok.

For Android app, if it ask for

READ PHONE STATE AND IDENTITY
Allows the application to access the phone features of the device. An application with this permission can determine the phone number and serial number of this phone, whether a call is active, the number that call is connected to and the like.

or

READ CONTACT DATA
Allows an application to read all of the contact (address) data stored on your device. Malicious applications can use this to send your data to other people

I will not download to my Android phone. I may download to my iPod Touch or iPad if I need. Thus, if someone say there are more iPhone app download than Android app, is wrong.

I play the game, why you need to read phone state and identity or contact data? The game and many application just need this permission:

FULL INTERNET ACCESS
Allows an application to create network sockets.

I have chess.com game and Huffington Post on both Android and iOS devices because they don't ask for the right to read my phone state or my contact data.

Is Pinger Textfree Good?

I don't think so. Few months ago, I installed Pinger Textfree app on my iPod Touch. I tested it by text to my own cell phone number. Few days later, I got a spam SMS sent to my cell. I owned this cell number for a long time and never got any strange text. I tested Pinger Textfree again. This time I text to my private Google Voice number. This number I had it for about a year and never use. Few days later, I got spam on my Google Voice number. Since Pinger Textfree allow user send to email, I created a new Yahoo email just to test Pinger Textfree. Yes, this brand new Yahoo e-mail got spam.

Since that time, I never use Pinger Textfree to send text or email to my friends. I don't want them got spam. On my iPod Touch, I will use Google Voice to text but not Pinger Textfree.
