It's the photos and videos that take a long time. You need to save them in another folder like this:
1.Connect iPhone/iPad to the computer.
2.If Scanner and Camera Wizard does not open automatically, choose Start > All Programs > Accessories > Scanner and Camera Wizard.
3.If a window appears asking you to select your device, choose your iPhone from the list and click OK.
4.When the Scanner and Camera Wizard launches, click Next.
5.Ensure that all of your photos are selected and click Next.
6.Enter a name for your group of photos and choose the location to which you'd like to import them.
7.Enable the option "Delete pictures from my device after copying them."
8.Click Next.
9.When the photos finish importing and deleting, click Next.
Click Finish.

I've been using multi-sim card for a few years now. You can have up to 5 sim cards in 5 devices with one phone number. However, only one sim card can be active at one time, meaning- only one device can be used to receive sms and voice calls. The other sim cards in your other devices/phone can still be used to make calls, send texts, surf, etc. They just can't receive any incoming calls or texts.

With the ipad, i'd just enable the sim in my phone active and use the sim in the ipad for data only.

If you enable the sim in the ipad, calls and sms'ses will go to your ipad and not to your phone. At that same time, you can use your phone to still make calls, send sms, browse web etc.
In a normal ipad, not sure calls will go through so most likely it will be sent to voicemail.

I think the multi-sim is for postpaid only. The monthly charge for additional sim is rm15. This is not including the charge for data, calls, sms.
