I found a few developers that are being busy to murge the android en windows systems true virtual machine and so on. Then I came to YouWave!
Youwave is a program that simulates the android on your pc and very easy. To use it you can download it grom www.youwave.com and install it. It comes with a 2.3 version of android.
The next thing is to put al your apk files into a folder where you want. If you backup your phone with for example titanium backup you can select al the zip files with apk in it, and extract them in this folder. In youwave you can choose the path to your folder and you can see install these apks onto the simulated android.
Not all apk's are allowed to be installed, but if you put them in your mail, dropbox or somewhere else, you can install them inside the simulated android just like you would do on your phone.
So I tried the next best thing, whatsapp. I installed it, (normally i would restorte from titanium backup, but this android doesnt have root yet) and entered my number. I received an textmessage on my phone, but waited till the 5 minutes where up. After that I chose the option voice to receive a call with the number and entered it.
And here you go, whatsapp on my pc to use and chat with my contacts for the time I don't have my phone.
It's also possible to use another number (old nummber, pre-paid) or perhaps if you don't have a phone wich has whatsapp you can do use it now on your pc. When people call you, you have your phone to answere it.
