One of the biggest drawbacks of owning an iPhone or iPad is that Apple doesn't offer a way for users to supplement the internal storage with an SD or microSD card like many Android devices do.
One way to get around the problem is to buy the largest capacity on offer, but the price tags means that's not an option for everyone. Another option is to add to the internal storage using an external wireless media hub.
There are countless devices that will do this job, but one I suggest you take a look at is the IOGEAR MediaShair Wireless Media hub because it brings a whole raft of features to the table. Not only can you plug an SD card (SD up to 2GB, SDHC up to 32GB, and SDXC up to 2TB), USB flash drive, or even a portable USB hard drive into the MediaShair hub and the built-in wi-fi can share the content with up to seven iOS or Android devices, it has a built-in battery that can be used to recharge your devices.
The device also supports pass-through, so you connect the hub to the internet-facing wi-fi connection, and then connect the devices to the hub to allow them to have web access. This way you have access to both the internet and your data.
Access to the data on the device from iOS and Android device is handled through a free app.
On top of that, if you're in a hotel that only has Ethernet connection, you can connect the MediaShair hub to the wired connection and share the connection wirelessly.
You can also connect the MediaShair hub to Windows and Mac PCs.
A solid device for road warriors (car charger included), BYOD and business users, and consumers looking to expand the storage on their mobile device without breaking the bank.
