Tamara,
You cannot upgrade a sde gdb to 10.1, without having Desktop 10.1. To upgrade the gdb to 10.1, you will have to install Desktop 10.1.
As far as for compatibility, YES the Desktop 10.0 clients can work with a sde 10.1 gdb.
Client and geodatabase compatibility:
http://resources.arcgis.com/en/help/main/10.1/index.html#//003n00000008000000
The above link mentions:
1. ArcGIS 10 can open and edit a 10.1 geodatabase. Be aware, though, that the ArcGIS 10 client will not have access to 10.1 functionality and will not be able to edit data, such as network datasets or mosaic datasets, that are using 10.1 functionality.
2. Your ArcGIS 10 clients should be patched to at least service pack 2 if you will be connecting to a 10.1 geodatabase.
When you make a connection between releases�??for example, if you connect from ArcGIS for Desktop 10.1 to an ArcSDE 9.3 geodatabase�??the functionality available to you is limited by the lowest release number. In this example, you would not have access to functionality available in 10.1 since the geodatabase is still at the 9.3 release. Similarly, though ArcGIS 10 clients can open, query, edit, and save data in 10.1 geodatabases, they cannot open datasets with 10.1 functionality. For example, you cannot access file geodatabases that were compressed using ArcGIS 10.1, the editor tracking fields in 10.1 feature classes will not be populated when connecting or editing from 10 clients, and you cannot use 10.1 network dataset or mosaic dataset functionality

Tamara,
The above is applicable only if the data that you are editing is using any new 10.1 functionality, which was not present in 10.0 !
For more reference on "What's new at 10.1", you can have a look at the below links:
What's new in ArcGIS 10.1:
http://resources.arcgis.com/en/help/pdf/whats_new_in_arcgis.pdf
What's new for editing in ArcGIS 10.1
http://resources.arcgis.com/en/help/main/10.1/index.html#//016w0000002v000000
If you simply upgrade your geodatabase to 10.1 and don't make any changes/add new functionality to your existing data using 10.1, you can edit the same data using Client 10.0 w/o any problem.

Tamara,
The same restrictions are applicable if you directly upgrade your sde gdb to 10.2.

The above link contains all the required information.
Hope this helps!
